About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles demanding actuation with a 375 mm stroke. The riveted round-body construction pairs a corrosion-resistant barrel and rod, outperforming painted alternatives in damp or washdown environments. Its 1/8" port and M8x1.25 male rod thread ensure straightforward integration.
Equipped with a built-in magnet for CMSG, DMSG, or EMSG switches, the unit accepts standard ISO 6432 mounting brackets. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to safely lifting an 8 kg load vertically with a 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impacts without requiring manual adjustment.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375SCA Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 157 N of thrust, with the stainless body surviving humid washdown cleaning cycles.
Textile Loom Tensioner
Maintains yarn tension across a 375 mm travel distance, relying on the CA pivot clevis to accommodate angular rod movement during operation.
Lab Sample Ejector
Extends to push test tubes out of a carousel, using the integrated magnet with a DMSG sensor to confirm full ejection before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375SCA the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm bore lowers the output to 100.5 N, while moving up to a 25 mm bore increases it to 245.3 N at 0.5 MPa. The CA rear pivot cover suits articulated clevis mounts, and the included magnet supports position sensing. Because the 375 mm stroke is relatively long, minimize side loading to prevent rod bending and premature seal wear.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the rod. To suspend a load securely during an air loss event, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI16-20 Stainless Steel Mini Cylinder MI20X375SCA FAQ
This 20 mm bore cylinder features a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston at stroke end and do not act as a brake. If air is lost, the rod will drift; use an external rod lock or pilot check valve to hold a suspended load.
